I have two Samsung M3 1TB external HDD's, and I leave both connected to my laptop through a USB hub 3.0. Sometimes their blue light turn off automatically if they're left unused for a while. But sometimes the blue light keeps turned on even though I'm not doing anything with them.
What is normal: for the blue light be turned on or off? Will they wear out if the light keeps turned on?
